Most of the songs in Madonna's "Drowned World Tour" show in Philadelphia on Saturday night -- her first concert tour in eight years and her first "Drowned World" performance in the U.S. -- were taken from her most recent albums, "Ray of Light" and "Music." The Material Mom, 42, completely bypassed some of her biggest hits, including "Vogue," "Express Yourself," and "Material Girl" (though she did sing "Holiday"). Also missing, noted the Associated Press, were the campy sexuality and party atmosphere of her earlier tours, replaced by a darker mood that included images of rape, references to murder and even sounds of gunfire. During the remorseful "Nobody's Perfect," a geisha-garbed Madonna (wearing a kimono with a 52-foot train) appeared vulnerable as an angry lover held a sword to her neck. During another number, a video image of a battered and bruised Madonna filled the screen before she entered, aimed a gun and fired. A Japanese Anime cartoon montage depicted women who were fighting, being abused, sexually objectified and, eventually, raped. At another point, she lampooned the violence depicted in some country songs, joking about a father being killed and apparently being barbecued later. Still, she could sing tenderly, too ("What It Feels Like for a Girl" was delivered in Spanish), and for fun, she rode a mechanical bull. Fans seldom stopped screaming.
